Question

function createImageDirectory ():void
var dir:File = File.applicationDirectory.resolvePath("Game
Images");
dir.createDirectory();
So Adobe is telling me that I am not "allowed" to perform the
above function? The most logical place for a player of my AIR game
to store their game images would be in a "Game Images" folder
located within the application directory.
If it's true that you're "not allowed" to create a simple
directory within the "applicationDirectory", then SHAME ON
ADOBE!!

Answer 1

We block access to the application directory because (a) it's
an insecure coding practice and (b) it won't work on all operating
systems, anyway.
This is not a particularly severe limitation in most
scenarios since you can instead store the data elsewhere. The two
most common locations are File.applicationStorageDirectory (good
for files the user doesn't need to see) and File.documentsDirectory
(good for files the user might want to find).
